摘要
以"Counter"、"晋番茄四号"、"109番茄"、"新星101"、"益丰"、"益丰三号"6个番茄品种为试材,对种子萌发期不同温度处理、幼苗期28℃温度下不同光照处理的番茄耐热性进行了比较,以期为番茄长季节越夏栽培选择耐热性品种提供依据。结果表明:34℃温度处理下,"109番茄"和"新星101"种子发芽率和发芽势、苗期热胁迫下的热害程度和热害指数、叶片MDA含量和相对电导率最强,"Counter"的耐热性最差,且品种间差异极显著。
Taking six tomato varieties ＇Counter＇,＇Jin tomato No.4＇,＇Tomato 109＇,＇Xx-101＇,＇Yifeng＇,＇Yifeng No.3＇ as materials,the effect of different temperature treatments on the heat tolerance at the stage of seedling germination were compared with different light treatment at 28℃ at the seedling stage,in order to screen heat-tolerant tomato varieties.The results showed that the germination rate and force of ＇Tomato 109＇ and ＇Xx-101＇ at 34℃,tomato seedling hot injury degree and index,the MDA content and relative electrical conductivity at heat stress were the highest,＇Counter＇ took second place,and the difference between them was extremely significant.
